A holistic leadership guide emphasizing the integration of the Inner Game (personal energy and resilience) and Outer Game (business performance). Drawing on his experience leading Siemens, Alcoa, and NEOM, Klaus explores managing physical, emotional, mental, and spiritual energy to achieve sustainable success. Practical tools like breathing techniques, NLP anchoring, and gratitude practices empower readers to navigate stress and maintain focus. Real-world examples, such as Captain Sullenberger’s “Miracle on the Hudson,” illustrate energy dynamics. The book offers a compelling framework for leaders seeking balance and excellence.
